"Unexpected exception when getting view part instance of view part "

Question

I have done what is written in the link and repaired the program in the control panel, but the above message keeps coming back. Now what should I do? Can I just delete the program and reinstall it?

Error message "Unexpected exception when getting view part instance of view part" after installation (sdl.com)
